About Our Metal 3D Printing Expertise

Tongyong Industries provides custom metal 3D printing solutions for global B2B customers, with production carried out through Tongyong Hardware's industrial-grade printers in China — producing complex, geometrically intricate parts that traditional machining can't achieve.

  • Titanium, aluminum, and stainless steel, serving aerospace, medical, and automotive clients
  • Single prototypes or low-volume production, balancing speed and precision
  • Design collaboration for 3D printing, reducing material usage through topology optimization
  • In-situ monitoring and post-processing (heat treatment, CNC machining) deliver ready-to-use parts after they're sintered and fully densified

Precision Metal 3D Printing with Structured Quality Control

Our quality system is built around prevention, not just detection. Every printed part is monitored in real time during the build, then verified through post-print CMM inspection before it leaves our facility, holding to the 3D printing tolerances your design requires.

In-House CMM & Additive Manufacturing Inspection

In-House CMM & Additive Manufacturing Inspection

Every part is checked against your CAD model on our coordinate measuring machines, with full dimensional reports provided for complex geometries that are hard to inspect by other methods — supporting high precision 3D printing even on internal lattice structures.

Frequently Asked Questions About Metal 3D Printing Services

Find answers to common questions about our metal 3D printing services, materials, processes, and manufacturing capabilities.

Better for low-volume production, rapid prototyping, and complex geometry that's difficult to machine. As volume increases, CNC typically becomes more cost-effective.

Common materials include stainless steel, aluminum, and titanium alloys, selected based on mechanical properties and application.

Both fuse metal powder layer by layer with a laser. SLM fully melts the powder, while DMLS sinters it at a lower temperature. The right choice depends on material and application.

For rapid manufacturing, prototype parts are typically delivered within days, since no tooling is required before production.
